WebAssemblyとBlazor 、WebAssembly System Interfaceでコンテナライズの設計を解説Takao Tetsuro
WebAssembly(WASM)とWebAssembly System Interface(WASI)は、コンテナライゼーションのアーキテクチャのひとつです。DockerやWSL(Windows Subsystem for Linux)と同じく、皆さんの業務ロジックにモビリティとスケーラビリティを与えてくれます。モビリティとスケーラビリティを考慮したプログラムを作る一例として、Rust、Nodeなどの技術を交えコンテナライゼーションを解説します。

Router WebSocket allows for WebSocket connections through CloudFoundry routers. Nginx is currently used to terminate HTTP connections and pass them to routers, but does not support WebSocket. The proposal is to modify routers to handle WebSocket connections directly by implementing a WebSocketConnection module that speaks the WebSocket protocol. This would allow routing of WebSocket traffic without relying on Nginx, improving performance and functionality for applications using WebSockets in CloudFoundry. A proof of concept implementation demonstrates routing of WebSocket connections through the router.
This document discusses using TypeScript for ServiceWorker development with ES6 modules. It proposes a strategy of using the ServiceWorker lifecycle to install and activate a TypeScript script, and intercept fetch requests to transpile TypeScript modules to JavaScript on the fly. Key aspects include skipping the waiting lifecycle with self.skipWaiting(), activating with claim(), and using postMessage to communicate between the ServiceWorker and main scripts during transpilation.
V8 is Google's open source JavaScript engine that is used in Chrome and Node.js. It uses several optimization techniques like hidden classes, inline caching, and TurboFan to improve JavaScript performance. V8 first parses JavaScript into an AST, then compiles it into bytecode which is executed by the Ignition bytecode interpreter or optimized by TurboFan into machine code using techniques like hidden classes to optimize property access and inline caching to optimize function calls.
This document discusses the past and future of asynchronous JavaScript. It covers callbacks, promises, generators, async/await, and asynchronous iterators. Key asynchronous concepts covered include setTimeout, callbacks, jQuery Deferred, Promise/A+, ECMAScript promises, problems with promises, generators with co, async/await, and asynchronous iterators at stage 3 of ECMAScript proposals. The document provides an overview of the evolution of asynchronous patterns in JavaScript.
The document discusses virtual DOM implementations. It explains that virtual DOM is used to more efficiently update the real DOM by maintaining a virtual representation of the DOM and only updating the real DOM with necessary changes. It provides examples of how virtual DOM libraries like React and Fuel work under the hood by using techniques like DOM diffing algorithms and caching to improve performance.
The document discusses garbage collection in JavaScript. It explains that garbage collection is a mechanism to automatically free up memory occupied by objects that are no longer reachable by the program. It describes how the garbage collector works by tracing references between objects, marking reachable objects, and sweeping to free up the memory of unreachable objects. It also discusses incremental garbage collection which performs the marking and sweeping steps incrementally to avoid pausing the program for long periods.
